Raw milling must produce sufficient feeq to sustain the required kiln production, meeting targets for fineness, chemica lcomposition and moisture. With multiple tasks.to accomplish, process flow and control …

The production capacity of a raw mill is generally lower than that of a cement mill. This is because the raw materials need to be ground into a fine powder before they can be used to produce cement. In contrast, the clinker produced in the kiln is already in a fine powder form and can be directly used to produce cement.

The production rate of the raw mill is 240,000 kilogram per hour. 4.
